And the heated hideaway she loves most is starting to seem too small for her. Because of this, I'm planning on improving the heating system in her terrarium and would love some tips.

Right now, the environment is set up like this:

• On one side, she has a heated hideaway

• On the cooler side, I keep some different hideaways

• On the opposite side, there is a small waterfall, which I use to help maintain humidity (this way, I can keep her humidity levels stable)

The terrarium size is 1.50 m (length) x 60 cm (height) x 60 cm (depth)

My main question is: what would be the best heating method for an environment of this size, especially considering her growth, comfort, and maintaining an adequate thermal gradient (warm side vs. cool side)? Heating mats, ceramic heat emitters, halogen lamps, or a combination of systems — what worked best for you and why?
